Understanding Compound Interest

The Power of Compounding

Compound interest is "interest on interest." It's calculated on the initial principal and also on the accumulated interest from previous periods. This creates exponential growth over time.

Formula

A = P(1 + r/n)^(nt)

Where A = Final amount, P = Principal, r = Annual rate, n = Compounding frequency, t = Time

Key Benefits

  • Time Advantage: Earlier you start, more you earn
  • Frequency Matters: More frequent compounding = higher returns
  • Exponential Growth: Returns accelerate over time
  • Passive Income: Money works for you automatically
